摘要

内蒙古自治区沙生灌木资源丰富,平茬而得的沙柳灌木枝条是很好的人造板原料。目前使用的沙生灌木削片设备均为国产BX216、BX218鼓式削片机,在使用中存在着功率不匹配的问题,生产能力仅能达到65%,且由于沙柳等灌木材的树皮含量高韧性大等特点,在加工过程中嫰稍部分切断困难,切断率不高,生产效率低。
为了解决上述切削问题,需要设计一种新型的切削机构代替,采用一组飞轮带动刀对沙柳材进行往复式端向切削,机构简单,安装方便,工作平稳。这种切削机构不仅使得沙柳材切口平整,切片质量好,而且切断率高,不会造成堵塞影响正常工作。
关键词沙柳材往复式切削切片质量
Abstract
The Inner Mongolia Autonomous Region, desert shrubs rich in resources, crop-derived from the Salix psammophila shrub branches is a very good man-made board material. At present the use of the desert shrubs chipper equipment are domestic BX216, BX218 drum chipper, in the presence of the use of power does not match the problem, production capacity could only achieve 65%, such as irrigation and because of Salix psammophila wood bark High content of the characteristics of toughness, in the process of tender slightly cut off part of difficulties, cut off rate is not high, low production efficiency.
Cutting to address these issues, the need to design a new body to replace the cutting, driven by a flywheel knife on Salix psammophila to build a reciprocating-cutting, institutions simple, easy installation, smooth work. Such institutions not only made the cut wood Salix psammophila incision formation, slices of good quality and high rate cut will not affect the normal work of the plug.

Key words :Salix psammophila wood reciprocating cutting slices quality
